To convert from a gas to an electric water heater, you need to disconnect the gas line, install an electric unit, and connect it to the electrical supply safely.
Switching from a gas to electric water heater can save energy and reduce maintenance. This guide covers everything from electrical requirements to installation steps.
Can You Convert Gas to Electric Water Heater?
Yes, you can convert from gas to electric. The process involves:
- Removing gas connections
- Installing proper electrical wiring
- Setting up the new electric unit
For safety, hire professionals if you’re not experienced with gas lines or electrical work. A licensed plumber can ensure proper installation.
Key Differences Between Gas and Electric Heaters
| Feature | Gas | Electric |
|---|---|---|
| Energy Source | Natural gas/propane | Electricity |
| Venting Required | Yes | No |
| Installation Cost | Higher | Lower |
| Efficiency | 60-70% | 90-95% |
Step-by-Step Conversion Process
1. Prepare Electrical System
Electric water heaters need 240V circuits. Check your breaker panel for:
- Double 30-amp breaker
- 10-gauge wiring
If your system lacks capacity, hire an electrician. The thermostat wiring must meet local codes.
2. Shut Off Utilities
Before removal:
- Turn off gas supply valve
- Shut off water supply
- Disconnect power to gas valve (if electric ignition)
3. Remove Gas Heater
Drain the tank completely. Disconnect:
- Gas line (cap the open end)
- Vent pipe (seal chimney opening)
- Water connections
4. Install Electric Heater
Follow manufacturer instructions for:
- Positioning the unit
- Connecting water lines
- Wiring electrical connections
Consider a smart thermostat for better efficiency.
Cost Considerations
Conversion costs vary by location and system requirements:
| Item | Cost Range |
|---|---|
| Electric Water Heater | $300-$1,500 |
| Electrical Work | $200-$800 |
| Plumbing Work | $150-$500 |
| Permits | $50-$200 |
Benefits of Electric Water Heaters
Energy Efficiency
Electric models convert nearly all energy to heat, unlike gas units that lose heat through venting. According to Energy.gov, electric heat pump water heaters can be 2-3 times more efficient.
Safety Advantages
No combustion means:
- No carbon monoxide risk
- No gas leaks
- No pilot light maintenance
Longer Lifespan
Electric heaters typically last 10-15 years compared to 8-12 for gas models. The lack of combustion reduces corrosion and sediment buildup.
Maintenance Tips
Keep your new electric heater running efficiently:
- Drain and flush annually
- Check anode rod every 3 years
- Test pressure relief valve yearly
- Insulate pipes and tank
For optimal performance, consider a descaling pump if you have hard water.
